Browning 40HQ100 Bushing Bore Timing Belt Pulley

40HQ100 is Browning’s 40‑tooth, 1/2" pitch gearbelt timing pulley built for split‑taper bushings (Q1) in H‑series belt drives. It features an outside diameter of 6.563 in, a pitch diameter of 6.366 in, a face diameter of 6.31 in, and a 1.25 in face width, all contained in a 2‑25/32 in overall width; it supports a belt width of 1 in and a bore through‑length of 2.5 in. The bore accommodates a range from 3/4 in to 2‑11/16 in, enabling shaft adaptation with Browning’s Q1 split‑taper bushings, and it uses two flanges to help locate and retain the belt. Designed for reliable belt tracking, the dual‑flange geometry keeps the belt aligned under load. This pulley is intended for synchronous drive applications in packaging, conveying, and automation equipment that use Browning H‑series belts, with an estimated maximum horsepower around 20 hp in properly matched systems. To install, pair 40HQ100 with Browning’s Q1 bushing and a matching drive shaft; the split‑taper bore provides secure clamping and precise concentricity. The pulley is compatible with the H‑series belt profile, offering a drop‑in solution where a 40‑tooth, 1/2" pitch pulley is required and a robust, bureaus of alignment is essential for high‑demand drive systems.
